Aqua-Sphere vs Lullaby
Aqua-Sphere and Lullaby come from the same Sherwin-Williams collection. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. The 23-point LRV gap — 65 for Lullaby vs 41 for Aqua-Sphere — means Lullaby will open up a space more effectively. Both share a cool character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 14.5 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Aqua-Sphere vs Lullaby in Real Spaces
2 real rooms side by side. Seeing Aqua-Sphere and Lullaby in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Living Room
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Lullaby reflects noticeably more light off the walls, making the space read more open than Aqua-Sphere.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Lullaby returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Aqua-Sphere vs Lullaby Simulated Comparison
5 simulated room previews — drag the slider on each to see Aqua-Sphere on one side and Lullaby on the other.
Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
